Abstract

This process is a method of accomplishing three requirements when attaching one cover to a mating front or rear cover. The requirements are alignment, fastening, and electrical grounding. This is accomplished without the aid of screws, but rather by snapping the covers together (see Figs. 1 and 2). (Image Omitted) Center cover 1 is made of steel and plated with nickel. End cover 2 is made of plastic and painted on the inside with conductive nickel paint. The objects labeled as stainless steel alignment and contact strips 3 are spot-welded to the center cover 1. The contact strips are made in such a way that they capture the lip molded on the front cover. This aligns the edges of the two covers. At intervals of approximately three inches along this strip, notches are made.
